SuperScan is a free connect-based port scanning software designed to detect open TCP and UDP ports on a target computer, determine which services are running on those ports, and run queries such as whois, ping, ICMP traceroute, and Hostname lookups.
ShieldsUP is an online port scanning service created by Steve Gibson of Gibson Research Corporation.The purpose of the utility is to alert the users of any ports that have been opened through their firewalls or through their NAT routers, which can be used by malicious users to take advantage of security vulnerabilities.
Ping Scan – Check host by sending ping requests. TCP/IP stack fingerprinting – Determining the operating system and hardware characteristics of network devices based on observations of network activity of said devices. Scriptable interaction with the target – using Nmap Scripting Engine [12] (NSE) and Lua programming language.
Network enumeration is a computing activity in which usernames and info on groups, shares, and services of networked computers are retrieved. It should not be confused with network mapping, which only retrieves information about which servers are connected to a specific network and what operating system runs on them.
Proxy scan - a proxy (SOCKS or HTTP) is used to perform the scan. The target will see the proxy's IP address as the source. This can also be done using some FTP servers. Idle scan - Another method of scanning without revealing one's IP address, taking advantage of the predictable IP ID flaw. CatSCAN - Checks ports for erroneous packets.
Once a successful scan is completed there is no trace of the attacker's IP address on the target's firewall or Intrusion-detection system log. Another useful possibility is the chance of by-passing a firewall because you are scanning the target from the zombie's computer, [ 10 ] which might have more rights than the attacker's.
Libprotoident supports over 200 different protocols and the classification is based on a combined approach using payload pattern matching, payload size, port numbers, and IP matching. [ 75 ] A French company called Amesys , designed and sold an intrusive and massive internet monitoring system Eagle to Muammar Gaddafi .
Nikto is a free software command-line vulnerability scanner that scans web servers for dangerous files or CGIs, outdated server software and other problems. It performs generic and server type specific checks. It also captures and prints any cookies received. The Nikto code itself is free software, but the data files it uses to drive the ...
